The best of the lot. Very funny script, brilliant cast, superbly acted. I prefer Edmund as this type of meek, slimy character than in later series. Also Balders is better suited as intelligent than stupid, that character is already brilliantly done by Percy. Each episode has a uniquely funny story. The Archbishop one where Baldrick makes holy artifacts is extremely funny. Especially as Percy thinks he bought a real artifact only to discover that it's one of Baldricks.
He marries an 8 year old princess in another episode. Very original humour, and the little princess herself is extremely funny. The way she laughs at the Vicar is hilarious. Witchsmeller Persuivant, another great episode, possibly the best but its difficult to distinguish which is the best as they are all so good. Frank Finlay is so believable as the witch, his voice, expressions, the way he cross examines Edmund in court and entraps him. Pure genius.
The last one is fantastic. I love the way he finally gets revenge on his dad by forming an army of the 6 most evil men in England. All with uniquely evil attributes. I don't think 6 episodes is enough for this first series. There is so much comedy there to fill 12 episodes at least. Still the second and third series, although inferior did not disappoint. The fourth however did.
Will always remain as one of the great British classics.
